Multiple Choice

The circuit being tested must be fully _______ form the supply prior to using the tester.

Explanation:
To test safely, you must remove any energy source so the tester isn’t exposed to live voltage or backfeed. The circuit being tested must be fully disconnected from the power supply before testing, ensuring there is no voltage on the circuit and no current can flow back into the supply or the tester. If it remains connected, it’s energized and dangerous; a floating or isolated state can still pick up stray voltages or leave parts with uncertain potential, while simply being connected guarantees live voltage. Fully disconnected from the supply is the safe, correct approach.
